SASH BALANCE AN D FASTEN'ER.

Application led August 18J 1921.

To all whom it may conce/m Be it knownthat l, HoRATIo R. SWART- woon, a citizen of the United States, resid ing at Kansas City, in the county of Jackson and State of Missouri, have invented a `certain new and useful Improvement in Sash Balances and Fasteners, of which the following is a specication.

My invention relates to improvements in sash balances and fasteners. l

ll`he object of my invention is to provide a simple, cheap and effective sash balance combined with means for locking the sash in the position to which it may be adjusted.

A further object of my invention is to provide a device of the kind described, which may be readily applied to windows already installed, which is durable and not liable to get out of order and which is efficient in operation.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates the preferred embodiment of my invention,

Fig. 1 is a front view, partly/in elevation and partly broken away, of a window provided with my improvement.

Fig. 2 is a vertical sectional view of the same.

Fig. 3 is an enlarged1 horizontal section on the line 3-3 of Fig. 1.

Fig. 4 is a vertical sectional view on the line 4 4 of Fig. 3.

Fig. 5 is a vertical sectional view on the line 5--5 of Fig. 1.

Similar reference characters designate similar parts in the di'erent views.

v `1 designates. an ordinary window frame having a jainby 2. 3 and 4. designate the upper and lower sashes` respectively, each of which is provided in one side edge with a vertical groove 5, in which is mounted avertical coil spring 6.

rlhe coil spring 6 which is mounted in the" tion, a description of the one which oper-v Serial NO. 493,380.

Each sash has secured to one of its side .L y

edges, a vertical plate 10 which covers the vadjacent groove 5, and which is provided with a longitudinal row of holes 11, see Fig. 2.

For releasably locking eachy sash in the position to which it may be adjusted, there are provided suitable means which may comprise two locks, each of which is mountedv in the frame 1 at one `side and near its middle, and each of which is provided with means for being manually unlocked.

As the two locks are Similar in construcates in connection with the lower sash is sulicient for both.

Referring to Figs. 3, 4 and 5, the lockcomprises a rectangular casing 12, having a removable side 13 and a vertical plate 14 which is fastened to the j amb 2 by screws 15.

Horizontally slidablv mounted in the cas ing 12 is a bolt 16, which at its outer end is adapted to enter any one of the holes 11 in the lower sash. For normally forcing the bolt to the locking position, it is provided with a longitudinal slot 17, in which is mounted a horizontalcoil spring 18, one lend of which bears against the bolt 16 and the other end of which bears against a proie@` tion 19, which extends inwardly into the slot 17, from the casing 12.

For manually retracting the bolt 16 from the locking position, the-re is provided in the casing 12 an oscillatable member 20 hav- 95 ing; cylindrical shouldered ends respectively mountedv in holes in the-front and rear'of tween the two arms ofthe bifurcated adj acent inner end of the bolt-16, and which is provided with two oppositely extending arms 21 which respectively engage on the same side two projections 224 on the bolt 16. Themember 20 is provided with a hole which extends. longitudinally therethrough, and whichis other than round in cross secv tion. Through this hole extends a horizontal .forwardly and rearwardly extending shank member 23 which fits the hole and which extends through a hole 24: in the frame 1. The member 23 is shouldered at its forward end, and is rotatably fitted in a hole in a plate 25 which is fastened to the inner side of the frame 1. A knob 26 is secured to the front end of the shank member 23.'

By turning the knob 26 in either direction, the shank member 23 operates to turn the member 20 so that the latter withdraws the bolt 16 from the locking position, andout of the adjacent hole 11 in the adjacent plate 10.

*TheV sash 4 may then be vertically adjusted to the desired position, after which the knob 26 is released,upon-which the spring 18 will vforce the bolt 16 to the locking position, in which the bolt will enter the hble 11 which is then in register therewith.

The lock for the upper sash isconstructed fand operated in the same manner, as abo-ve described, the shank 23 ofthe upper lock being longer to correspond with the greater distance of the casing of the upper lock from the inner side of the window frame.' v

The springs 6 are preferably of suilicient strength to lift the sashes to their uppermost positions.

To raise the lower sash, it is but necessary to operate the knob 26 of the lower lock so as to withdraw the adjacent -bolt 16 from the locking position, upon which the adjacent .Y ,The'holes 11 may .be so arranged as t0 permit both sashes toJoe locked in the closed "position: p

B havingthe coil springs 6 located in longitudinal grootes in the 5 edges ofthe sa'shes', longitudinal slotting of the jambs is avoided, andthe invention's applicable to window frames h avingsi'ngle jambs fittedv against brick -or' stone, or against` studding,

this constructionthe plates 10 KA'serve th'edo'uble function of locking plates, and co-oper-L as well to :With

the casing 12, and which is mounted be;`

ate with the sashes tQfOrI-m housings for the coil su ortin -s rin By iliving heploc located in the window frame, the knobs 26 are each located permanently at one place, so that a person can readily locate them in the dark.

I do not limit my invention to the structure shown and described, as modifications within the scope of the appended claims may be made without departing from the. spirit of my invention.

What I claim is:-' .x j 1. In a sashbalance and fastener, the combination with a windo-w frame and a sash slidable therein, of a plate secured to the sash. and having a vertical row of holes, a bolt adaptedto be moved on said frame into 'and out of any one of `said holes, and a vertical coil spring supported by the frame and supporting the sash, substantially as set forth. o

2. In a sash balance and fastener, the combination with .a window frame and a sash slidable therein, of a vertical coil spring supported by the frame and supporting the sash, bolt engaging means on said sash, and

a lock mounted on the frame and comprising a casing, a bolt slidable in the casing, a spring normally forcing the bolt into engagement with said bolt engaging means, and manually operated means for retracting the bolt from said position, substantially as set forth.

3. In a sash balance and fastenenthe combination with a window frame, of a sash slidable therein having in one side 'edge a vertical groove, a vertical coil spring supported by the frame and mounted in said groove and attached to and supporting said sash, a vertical plate fastened to saidl sash.

and covering said groove and having a vertical row of holes, a lock casing mounted in lsaid frame, and a bolt mounted in said casing and movable to and from a'positionl in which it is adapted to enter any one o`f said holes, substantially as set forth.

' 4. In a sash'gbalance and fastener, the combination withfa window frame, ofa sash slidable therein having in one sideedge a vertical groove, a vertical coil spring mounted in said groove and having its uppers/endY attachedtothe frame and its lo eren'd attached to thesash, a vertical pl, te attached to said edge and having a vertical row of holes, a lock casing mounted in the frame, a bolt slidable 1n sald casing to and from aposition4 in which itis adapted to enter any oneof said holes, a spring for forcing the bolt to a -lockmg position, and. manually operated for retracting theboltfrom the locking position, substantially as set forth,

5. iin a sash balance and fastener, the to and supporting the sash, and releasable combination with a window frame, ofa means forlocking the sash to the frame,`sub sash slidable therein having in each longistantially asset forth.- x (tudinal edge a vertical groove, two oeil In testimony whereof l have signed my 5 springs having their upper ends supported name to this specification.
